Item price scaling later on is way too disproportional to income. Earn 3000/level and top tier items cost 60000 each?!? It'd take forever to buy all items. Other than that, great game. But I'm done playing after the "main" mission.
So I found a gold bag. The description said "you can sell it". So I sold it. A couple minutes later I discovered it was a unique quest item. Now I can't complete that quest. :/
Warning added now.
